Changed "Exception Points" to "Exceptionpoints" in the debugger
documentation and help. This better matches "Watchpoints" and
"Registerpoints". Also, it's very confusing that you see the help topic
listing showing "Exception Points" but typing "help Exception Points"
doesn't actually work.
cpu/e132xs: Fixed a flags issue in the recompiler.
misc/dgpix.cpp: Demoted The X-Files to not working with unemulated
protection.
skeleton/turnierdart.cpp: The srcclean on this file was missed.
- Added exception points as a new class of "points" triggering on specific exception numbers, with a similar set of commands to breakpoints and registerpoints.
- Removed the per-instruction callback hook from device_debug. Only one driver was using this (rmnimbus.cpp), and what it was doing with it could be done more cleanly with exception points.
- Change the type of the action string parameter for "points"-creating methods and make some parameters optional for those.
- Change trace file logging to use a std::ostream instead of FILE * to take better advantage of strformat.
